Why does ice float in liquid water?

a.) The liquid water molecules have more kinetic energy and thus support the ice.
b.) The ionic bonds between the molecules in ice prevent the ice from sinking.
c.) Ice always has air bubbles that keep it afloat.
d.) Hydrogen bonds stabalize and keep the molecules of ice farther apart than the water molecules of... show more a.) The liquid water molecules have more kinetic energy and thus support the ice.

e.) The crystalline lattice of ice causes it to be denser than liquid water.

ice floats in water because ice has less density than water.
ice is formed at 0 degreen celcius and water contracts upto 4 degree celcius and the it begins to expand. its net expansion is more than its contraction.d.) Hydrogen bonds stabalize and keep the molecules of ice farther apart than the water molecules of liquid water ' is also a reason behind it.

Ice floats because it is about 9% less dense than liquid water. In other words, ice takes up about 9% more space than water, so a liter of ice weighs less than a liter water. The heavier water displaces the lighter ice, so ice floats to the top. One consequence of this is that lakes and rivers freeze from top to bottom, allowing fish to survive even when the surface of a lake has frozen over. If ice sank, the water would be displaced to the top and exposed to the colder temperature, forcing rivers and lakes to fill with ice and freeze solid.
